Administrative history

In 1961 part of the Propane Bubble Chambers Group of the Proton Synchrotron Division (PS) became in a newly created division called Nuclear Physics Apparatus Division (NPA) was directed by Colin Ramm. Its mission was the design, development and construction of apparatus for the experimental programme including the beam transport equipment for bubble chambers.

In collaboration with laboratories outside CERN NPA was responsible for high energy physics programme at the PS, using heavy liquid buble chambers.

NPA Division received the 1 meter heavy liquid chamber called BP3 from the Ecole Polytechnique (Paris) and directed the construction of the CERN 1 metre propane chamber.

In 1963 NPA Division became involved in the neutrino physics research programme.

In 1966 NPA joined PS Department directed by P. Germain. It was also designated as host for Gargamelle, the Large Heavy Liquid bubble chamber under construction at CEA Saclay.

In 1969 NPA Division ceased to exist. Some staff remained in the PS Department whilst most were transferred to the Track Chamber Division of the Physics II Department, directed by Charles Peyrou. TC Division became the division responsible for the high energy physics program at the PS using bubble chambers (Hydrogen Bubble Chambers + Heavy Liquid Bubble Chambers).
